The seeds they eat are not digested at all. The seeds come out in the form of faeces(water material of the body). Since animals move from one place to another, the seeds in their stomach also goes. When they excrete, the seeds come out and thus they are dispersed from the original place.</p> <p>as when they Move; the pollengrains move with them and fall on certain place</p> <p>Animal dispersal:There are of multiple ways animals can aid in seed dispersal. Seeds can pass through the digestive tracts of animals, be transported in mud attached to hooves and hide, and sprout from seed caches. Knapweeds seeds and seedheads cling to fur like burrs. The sharp thorns on yellow starthistle seedheads can jab into passing animal hide. Small barbs on cheatgrass and medusahead seeds facilitate being picked up by feathers and fur.</p><p>Human Dispersal:Human play a big part in seeds dispersal today. Seeds stick into socks, shoes, and other clothing. Vehicles and farm machinery can get seeds and plant parts caught underneath. Transported soil, animal feed, and seed can contain weed propagules. We are particularly adept at weed dispersal because we travel both frequently and over long distances.</p> <p>as when they moved,the pollenhrains move with them and fall o certain place</p> | |
